[CF-metadata] Standard_name proposal for volcanic ash and radioactive particles

Dear Barbara and list,

I agree with you that both volcanic ash and nuclear particles are
insufficiently reflected in the standard-name table and we need a
proposal for new names.

We have 'atmosphere_mass_content_of_volcanic_ash' which is the column
load and for concentrations, we have mass_concentration_of_*_in_air so I
would slightly modify your parameter and propose:

mass_concentration_of_volcanic_ash_in_air
canonical units: g/m^3
description: Mass concentration means mass per unit volume and is used
in the construction mass_concentration_of_X_in_Y, where X is a material
constituent of Y. "Volcanic_ash" means the fine-grained products of
explosive volcanic eruptions, such as minerals or crystals, older
fragmented rock (e.g. andesite), and glass. Particles within a volcanic
ash cloud have diameters less than 2 mm. "Volcanic_ash" does not include
non-volcanic dust.




Concerning radioactivity, the situation is more difficult. I would say
we have 2 basic types: concentrations in air and depositions, and the
time-integral of the first. I would call depositions 'surface_content'
in CF, since content is defined as: a quantity per unit area. I propose
the following:


activity_concentration_of_X_in_air (Bq/m3)
Description: Activity concentration means activity per unit volume and
is used in the construction activity_concentration_of_X_in_Y, where X is
a radioactive material and activity denotes the number of decays of the
material per second.

surface_activity_content_of_X (Bq/m2)
Description: "surface" means the lower boundary of the atmosphere.
"Content" indicates a quantity per unit area. activity of X means the
number of radioactive decays of the material X per second.

The first is often integrated over time for dose-calculations, i.e.
integral_wrt_time in CF-nomenclature:

integral_wrt_time_of_activity_concentration_of_X_in_air (Bq*s/m3)
Description: The phrase "integral_wrt_X_of_Y" means int Y dX. The data
variable should have an axis for X specifying the limits of the integral
as bounds. "wrt" means with respect to.  Activity concentration means
activity per unit volume and is used in the construction
activity_concentration_of_X_in_Y, where X is a radioactive material and
activity denotes the number of decays of the material per second.



The tricky part is the X here, which is a very long list of radioactive
isotopes. I attach the list which is in active use for us, i.e. 383
nuclides including a few meta-states and chemical speciations in
particular for Iodine. Usual names for thes ar the second and third
column, i.e. H3, Na24, Ar41, Ge77m, Ge77 ... In CF, it is most common to
have these names in the standard-name (X in above proposals) I'm not
sure if it is practical possible to add these 4*383 standard-names to
the list? If it is just a question of formatting, I can try to do that.



Best regards,

Heiko
